Reference: AQA
Data produced by tallying the frequency of codes, allowing for easier comparison, identification of patterns, and subsequent statistical analysis.
Numbers that record how much or how many, such as reaction times, scores on a memory test or tallies of aggressive acts.
Recorded as numbers, it is objective, quick to analyse and easy to compare across conditions, but it strips out meaning.
Numerical data that are open to descriptive and inferential statistics.
